Why SO much pain only at 2 cm?

tmp-9166839

Im in so much pain when I get in and out the car, roll over, get off the couch, walk, simply STAND etc. The pain is in my lower stomach and obviously gets way worse during braxton hicks and baby movements.  Found out I was still at 2cm today and wanted to cry because if this is how much 2 hurts I can only imagine how much worse it will get!!!!! I was 60% effaced last week and Im sure it went up since then but doc didnt tell me how much today.

 

However, when I was 2 cm dilated with my son, I didn't even know and felt fine and normal.. even though my belly was way huger etc.  WHY all this pain? What could be causing it?
